The sleeve 68 is iixed to I claim: 50 a tube 70 of considerably smaller diameter 1. An apparatus comprising a spray the packing' 78. by means oi a series of studs prising a pipe, a nozzle fixed to one end oiI than the tube 62 which passes downwardly nozzle, and a testing rod movable axially throughthe supply chamber and through a through said nozzle.

stuiiing box 7l carried on the lo-wer face 2. An apparatus comprising a spray` of the base plate 24, this stufling' box-being nozzle, and a testineP rod movable through 55 provi-ded with a tightening gland 72 and a said nozzle.

These studs have collars 76 formed spaced grooves longitudinally thereof for ereon for retaining' a bracket element 77 the passage of fluid, a sleeve longitudinally which projects downwardly below the tube adjustable through said sprayer and having lor a purpose to be later described. Ina tapered upper end forming' a needle valve termediate the ends of this bracket is xed for the outer end of said nozzle, and a test` a pointer 78 projecting in proximity to an ing rod passing through said sleeve and index mark 79 formed on the tube 70 A movable axially thereof.

A device of the class described compressure may pass up around the pipe 70 prising' a nozzle, a needle valve for said within the sleeve 62 and thence through the nozzle, means for adj ustingsaid needle utings 66 and out through the nozzle elevalve relative to said nozzle, a rod posiment 64C around the `valve nieniber 69, this tioned axially within said valve, and means 75 construction forming in effect a needle valve y which said rod may be moved axially of spray nozzle. said valve.

n order to provide means for determin` A device of the class described com` This rod 81 projects throng' a stuling box hereof. 85

rests on the lower end of the bracket arm end of said nozzle, a needle valve adjustable 90 thereunder at 84 for this purpose. end cooperating' with said endy of said aving thus described one embodiment nozzle, and a rod axially movable throuo'h of this invention, it should be 'evident to said valve projectable and retractable be-. those skilled in the art that many changes yond the conical end thereof. c 95 and modilications might be made therein In testimony whereof I yhave aiiixedmy without departing' from its spirit or scope signature.

as defined by the appended claims. WILLIAM TEiVART.
